    /**
    @brief
        The EventMultiTrigger class is the equivalent of the @ref orxonox::EventTrigger "EventTrigger" class for MultiTriggers.
        Consequentially what it does is it provides a way to have a MultiTrigger triggered by any kinds of @ref orxonox::Event "Events".
        @ref orxonox::Event "Events" that are not caused by a MultiTrigger, or that are caused by a MultiTrigger with an originator that is no target of this EventMultiTrigger, are broadcasted to all entities that are the target of this EventMultiTrigger. @ref orxonox::Event "Events" that are caused by @ref orxonox::MultiTrigger "MultiTriggers" with an originator that is a target of this EventMultiTrigger just trigger the EventMultiTrigger for the originator that caused the MultiTrigger to trigger. Thus showing the equivalent behavior to the @ref orxonox::EventTrigger "EventTrigger".

        Example:
        @code
        <EventMultiTrigger invert="true">
            <events>
                <trigger>
                    <MultiTrigger ... />
                    <EventListener ... />
                </trigger>
            </events>
        </EventMultiTrigger>
        @endcode
